Since 1996, The Northshore Inline Marathon has been the largest non-profit inline skating marathon in North America. Held in Duluth, MN, the marathon course is enjoyed by thousands as one of the most beautiful stretches of road in America. Many participate in the marathon as an excuse to see the scenery.

Inline Warehouse has partnered with K2 to offer a fun incentive to skate in this 19th Annual NSIM marathon: a Costume Contest!
